Here Comes the Cloud
In the past couple of years the term “cloud” has been on every tech news headline from companies offering “cloud” computing or start-ups running killer “cloud” based services. After a lot of thinking and rewriting I decided “cloud” can mean different things, it all depends on how it is being referenced. For example “cloud” by itself is short for Internet or long for web. (…) Cloud-computing has also began to infuse itself into different BSD flavors: Amazon’s Elastic Compute Cloud (EC2) offers users the choice of FreeBSD and NetBSD AMIs (Amazon Machine Instances). Where as RootBSD offers users a choice of BSD on Xen based virtual private services with full technical support.
Developing Applications Using mport
In the February issue, you saw how to use the mport system as an end user. In MidnightBSD, you can access the mport features as a developer and add support for mport to your existing C, C++ or Objective C application. (…) The mport library allows developers to integrate some or all of mport features into their own applications without calling exec(). This article is just an introduction to the many features available to MidnightBSD application developers. I would recommend going to the MidnightBSD website for further information.
Taking the BSDA Certification Exam
The first article in this series (in the February 2012 issue) addressed some common misconceptions about certification and described why you should be BSDA certified. The second article in this series (in the March 2012 issue) discussed how to prepare for the BSDA certification exam. This article will provide some background information on how the exam is delivered and why. It will then describe where to take the exam and how to arrange for an exam if there currently isn’t an examination event or testing center near your location.
Installing OpenBSD 5.0 on VMware Server
We’re going to install OpenBSD 5.0. With the information in this article, you’ll learn how to install it both on your own computer and via VMware Server. For my example, I’ll use my own Bsdvm.com account.
Installing FreeBSD on Amazon AWS EC2 Cloud Services
I have had an AWS account since Amazon first introduced the Elastic Compute Cloud (EC2). But to be honest back in the day it was fairly cryptic to get an instance running, the AWS web interface was in it’s infancy and documentation was limited. From this article you will learn how to install a FreeBSD on Elastic Compute Cloud and run a Virtual Server on the Cloud.
In the previous articles we saw ho to set up a PostgreSQL cluster, how to manage backups (either logical or physical) and how internally transactions work. In this article we will see how it is possible to replicate a running cluster to another instance in order to have a fully mirrored and active “stand-by” node. Most of the configuration will be done by simple shell scripts in order to both show required instructions and to allow readers to replay several time the experiments. Please note that configurations shown in this article are for didactic purposes only, and represent only a starting point for replica environments.
Interview with Mark Price
I don’t think cloud is anything specifically new. I think its just a term that describes the trend in businesses outsourcing more IT functions. My experience with IT people in general is that IT people are very possessive and territorial, wanting to have lots of servers doing lots of things in-house. The ‘cloud’ idea just says “OK, we are going to outsource some of this boring technology stuff and instead concentrate on what’s really important to us”. Read the interview with President of Tranquil Hosting and owner of RootBSD to find out what is his view on the Cloud.
The Greater Benefits of Open Source Software
In contrast to proprietary software produced by most commercial manufacturers, Open Source software is written and perfected by volunteers, who freely share the programming code that would otherwise be kept secret. (…) Let’s address Open Source as a market phenomenon, stating some of the basic facts and seeking to clarify some misconceptions that have emerged in recent treatment of the issue.
